Polydan 4 Basement
High performance SBS elastomeric modified bitumen membrane engineered for deep foundations, underground tunnels, and basement retaining walls subjected to water pressure.
Key Features and Benefits
- SBS elastomeric polymers:Exceptional flexibility and elastic recovery absorb structural settlement
- Low temperature pliability:Stays pliable down to minus 15 degrees C without cracking
- Self healing characteristics:Bituminous compound flows around minor nail penetrations
- Continuous water barrier:Withstands continuous high hydrostatic groundwater pressure
